Quality made Winchester Super-X Power Core 95/5 Lead Free Centerfire Rifle Ammunition is best used in hunting, especially when targeting larger animals, as this ammo is made to have stopping power. It is made up of 95% copper and 5% zinc alloy, making it stronger and flexible.

The materials were intentionally created for bullets, and the weight is noticeably lighter when compared to a lead core projectile. The Nosler E-tips were generated from alloy. The nose and cavity in the power core are shaped to provide an exact hollow point to intensify the expansion window, which may result in an increase of expansion up to 400 yards.
